Q1: How long does it take to fully charge a battery?
The fastest charging power for one battery is 6200W. It takes about 92 minutes to charge one battery from 0% to 100%. If stacked on two or more batteries, the maximum charging power can reach 8800W, taking about 1 hour and 56 minutes to charge two batteries from 0% to 100%.
Q2: Can an EcoFlow DELTA Pro Ultra Battery charge without the EcoFlow DELTA Pro Ultra Inverter?
No. The EcoFlow DELTA Pro Ultra Battery needs to be connected to an EcoFlow DELTA Pro Ultra Inverter to charge. EcoFlow DELTA Pro Ultra is not compatible with third-party inverters.
Q3: Is EcoFlow DELTA Pro Ultra compatible with third-party inverters?
EcoFlow DELTA Pro Ultra is not compatible with third-party inverters.
Q4: Can I program EcoFlow DELTA Pro Ultra to run at certain times, like during peak rate hours?
Yes, charging times can be set.
Q5: What is the Bluetooth version?
EcoFlow DELTA Pro Ultra's Bluetooth version supports 4.2 and 5.0.
Q6: Can EcoFlow DELTA Pro Ultra/EcoFlow Smart Home Panel 2 run without the EcoFlow app?
EcoFlow Smart Home Panel 2 requires the EcoFlow app to run. EcoFlow DELTA Pro Ultra works without the EcoFlow app, but it is recommended for convenience.
Q7: What is the maximum input wattage for AC charging using a 240V load?
When using the C20 outlet and charging at 240V, the maximum charging input is 3000W. AC output is turned off at this time.
Q8: Is AC passthrough possible with a 120V input?
Use the C20 outlet for a bypass mode with a 120V input. There is no bypass mode for 240V input.
Q9: What is the EcoFlow DELTA Pro Ultra Inverter's surge rating, and how long does it last?
LRA 120A; 10.8kW peak watts for 10 seconds.
Q10: Can an electrical appliance plug directly into EcoFlow DELTA Pro Ultra?
Yes. EcoFlow DELTA Pro Ultra (Inverter + Battery) works as a standalone unit powering electrical appliances of up to 7200W. There are 11 outlets on the inverter, including NEMA 5-20, TT30, L14-30 supporting 30A, USB-C, and USB-A.
Q11: What is the charging power and time of a single battery?
With only one battery pack, the fastest charging input is 6200W, taking about 92 minutes to charge from 0% to 100%. When there are two battery packs, the fastest charging input is 8800W, and it takes about 1 hour and 56 minutes to charge from 0% to 100%.
Q12: Can EcoFlow DELTA Pro Ultra power a several-ton air conditioner?
One EcoFlow DELTA Pro Ultra can power a 3 ton central air conditioning unit. 2 x DELTA Pro Ultra can power two 4-ton central air conditioning units, 3 x DELTA Pro Ultra can power three 4-ton central air conditioning units, but the LRA rating must be within 120A.
Q13: Can X-Fusion charge EcoFlow DELTA Pro Ultra from an AC outlet while it's also plugged into the Smart Home Panel 2?
X-Fusion technology ensures that all AC output sockets provide optimal output in terms of wattage and amp. In fast charging mode, the output will always be 7.2kW, no matter how much the input is. When EcoFlow DELTA Pro Ultra is connected to Smart Home Panel 2, AC charging is disabled. 5 + 8 ports and C20 charging port mutual exclusion.
Q14: Can EcoFlow DELTA Pro Ultra charge from a 15A AC outlet while delivering 240V?
When charging EcoFlow DELTA Pro Ultra with 120V, it can output 240V normally. When charging EcoFlow DELTA Pro Ultra with 240V, it cannot output 240V. When charging at 240V using X-Stream charging via an AC inlet, AC output is not available. That is to say, when charging with high voltage 240V input voltage, all AC output is disabled.
